main prosthetic riskwas related to the removable provisional restoration during the postextraction healing phase. Treat- ment alternatives involving dental implant therapywere dis- cussed with the patient (timing of implant placement and load, need for grafting, restoration type, and treatment time).

TREATMENT PLANNING

Utilizing the information from the clinical and radiograph- ic examination aligned with the evidence in the literature, it was determined that we would proceed with the extrac- tion of tooth 11 and perform a ridge preservation graft.

SURGERY

At the time of surgery, anesthesia was accomplished with nerve blocks using lidocaine 2%with epinephrine 1:100,000. The surgical approach involved a minimally invasive tech- niquewith no flap elevation during the extraction of tooth 11 (Figure 4). The apical lesionwas removedwith hand curettes, and the socket was cleanedwith a carbide round bur used in reverse (Figure 5). The socket was augmented with allograft corticocancellous chips and a collagenmembrane (Figure 6). A vacuum-formed Essix retainer with an acrylic resin dupli- cate of the patient’s crown was used as a provisional restor- ation. Attention was given to the intaglio contours of the restoration so as not to apply excessive pressure to the site.
